offer bespoke design solutions that can be
manufactured and assembled in-house.
One of the crucial aspects of the design
was the detection and prevention of air
bubbles which can substantially corrupt
the analysis results.
Coupled with the client's requirement for
a transparent inspection window, it was
essential that the Bürkert designers avoid
any rough surfaces, dead zones and sharp
edges while creating the new dosing unit.
The engineers developed an injection
moulded component that would house
the control elements and machined it in
such a way that all of the internal passages
had a very high quality surface finish.
The control valves, based on the Type
0127 solenoid valve and the Type 6628
Twin Power rocker solenoid valve, were
positioned to minimise dead zones and
deliver maximum flexibility of control.
The Bürkert solenoid valves
have been specifically
designed to deliver complete
back pressure tightness,
excellent flushability and a low
internal volumewhile offering
precision switching of micro
volumes.
In addition, the basic design of these
solenoid valves ensures complete fluid
separation that enables them to be used
with aggressive fluids, which is essential
for applications using specific cleaning
chemicals as part of the process.
The cooperative approach to the design
and manufacture of the new dosing
unit has brought together technological
innovation and a desire to overcome the
technical challenges associated with the
development of a unique solution.
Bürkert Fluid Control
Systems is one of the
leading manufacturers
of control and
measuring systems for
fluids and gases.
The
final
design
can
be used
in a number of
analysis devices, thanks
to its flexibility, which means that the
overall demand for the product increases.
This increases the demand for components
and reduces manufacturing costs, making
the new dosing unit a very cost effective
project for the client.
